Sugar methyltransferases often (MTs) are a vital class of tailoring enzymes that catalyze the transfer of a methyl group from S-adenosyl-L-methionine to sugar-based N-, C- and O-nucleophiles. Whilst sugar N- and C-MTs involved with all-natural solution biosynthesis have already been discovered to act on sugar nucleotide substrates just before a subsequent glycosyltransferase reaction, corresponding sugar O-methylation reactions studied thus far occur after the glycosyltransfer response. Herein we report the primary in vitro characterization applying H-1-C-13-gHSQC with isotopically labeled substrates as well as the X-ray framework determination at Leucovorin Calcium one.fifty five angstrom resolution of the TDP-3'-O-rhamnose-methyltransferase CalS11 from Micromonospora echinospora. This study highlights a one of a kind NMR-based methyltransferase assay, implicates CalS11 to become a metal- and basic acid/base-dependent O-methyltransferase, and like a initial crystal framework for any TDP-hexose-O-methyltransferase, selleck chem inhibitor presents a brand new template for mechanistic scientific studies and/or engineering.
